I've been cutting hair for 20+ years my first pair of shears were the Nic STS 51/2". They have lasted 17 years and are still cutting today. I wanted a new pair so why change brands. I found tri-cut carried them and immediately ordered a new pair (6"). I know these will last for quite some time. Tri-cut was ease to work with. I called one day to ask questions and was able to talk with someone. This doesn't happen easily these days. They were nice and professional and answered what I needed. I ordered my shears and they showed up a few days later, very quick service. I would definitely order from them again...Thanks
